Abstract: ABSTRACT OF THE DISCLOSURE            In a microwave landing system or MLS, the bearing and/or elevation angular messages are in two parts a preamble transmitted by a sector antenna and a specific message transmitted by an electronic scan or scanning  beam antenna. As the gain of the sector antenna is below that of the scanning   beam antenna, the preamble is much more vulnerable to scanning than the message.          According to the invention, a preamble is transmitted, which is reinforced in a narrow angular sector and movable so as to cover the sector covered by the sector antenna by superimposing the radiation patterns of the sector antenna and the scanning   beam antenna in said direction.            (Fig 6).

Abstract: ROOM TEMPERATURE STABLE, HEAT ACTIVATED              ORGANOPOLYSILOXANE COMPOSITIONS     Abstract Organopolysiloxane compositions which react by way of a hydrosilylation reaction to undergo an increase in viscosity have improved resistance to reaction at room temperature (longer pot life) and/or an improved reaction rate at elevated temperature (shorter cure time) than analogous compositions of the art by incorporating therein an unsaturated hydrocarbon having from 6 to 10 carbon atoms, a terminal acetylenic linkage and an olefinic linkage conjugated therewith.  The resulting compositions are useful for preparing various cured siloxanes such as resins, elastomers, gels and foams.

Abstract: ENHANCED HYDROGEN RECOVERY FROM      LOW PURITY GAS STREAMS                     Abstract of the Disclosure A high pressure gas stream having a hydrogen content of up to about 90 mol percent is passed to a separator containing a permeable membrane capable of selectively permeating hydrogen.  The separator is used to achieve a bulk separation of the desired hydrogen from impurities contained in the gas stream.  The separated hydrogen is recovered at a reduced pressure and is passed to a pressure swing adsorption system adapted for operation at said reduced pressure.  The off-gas from the separator is recovered essentially at the higher pressure of the gas stream.  A portion of the off-gas is throttled to a lower pressure, with appropriate power recovery, and is passed to the pressure swing adsorption system as a co-feed gas, thereby contributing to the recovery of purified hydrogen product and to a reduction in the operating costs for the desired hydrogen separation and purification.  The remaining off-gas is recovered as a relatively high pressure fuel or feed gas for other purposes.

Abstract: ABSTRACT      A method and apparatus are provided for measuring the viscosity of a fluid medium such as drilling mud.  A rotary member is mounted within a housing for free rotation and viscous drag means applies a torque-induced rotation to the rotary member. The rotary member has a portion moving adjacent to a fixed surface but out of contact with the fixed surface, thus defining a fluid cavity in which the fluid medium to be tested can be placed, in order to be sheared by relative movement between the portion and the fixed surface.  Means are provided to measure the rotational speed of the rotary member, whereby the geometry of the fluid cavity and the nature of the viscous drag means can be used in a determination of the viscosity of the fluid medium to be tested.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for cutting through a web of flexible material for making tubular containers is described.  The web is partially formed into its final shape and to this end it has longitudinal fold lines and spaced lateral incisions which permit marginal portions of the web to be folded over and overlap at their free edges.  At a later stage in the making of the tubular containers it is necessary to accurately position the web so that it is cut completely through exactly where the lateral incisions are located. In the application of the invention, the edges of the web defined by the incisions form a stop which engages a cutter thereby accurately positioning the web for cutting.

Abstract: Title Pressure Plate Strap Drive Apparatus And Method Abstract of the Invention A strap drive 50 is employed for connecting a pressure plate 20 to a cover assembly 31 in a clutch 10.  The strap drive provides a fixed concentricity of the pressure plate relative to the cover assembly during assembly of the clutch, and provides a method whereby misalignments due to weights and clearances of mating clutch parts may be avoided.  A preferred method of insuring proper alignment of a clutch pressure plate includes the steps of forming a subassembly 80 to realign the pressure plate with respect to an adaptor ring 32, and fixing the subassembly to a flywheel 12 as an intermediate assembly procedure.  The result is an avoidance of misalignments normally introduced during assembly, and which produce undesirable vibrations during operation of the clutch.

Abstract: ABSTRACT DIGITAL CIRCUIT TESTING ARRANGEMENT In order to test a digital circuit, such as a digital logic circuit 100, for faults, during the first three cycles of a test operation of many cycles in duration, a predetermined input word is delivered to the input terminals of the logic circuit.  Throughout the remaining cycles of the test operation, each output terminal of the circuit is connected by an input multiplexer 200 to a fixed different one (or more) of the input terminals, whereby output of each cycle serves as input for the next cycle of the test operation.  A counter 300 counts the number of test operation cycles and sends an enabling signal to s signature detector 400 when the counter counts a predetermined number of test cycles.  Finally, in response to this enabling signal, each output terminal's output bit developed during the last cycle of the test operation is compared by the signature detector 400 with the corresponding "correct" bit.  Any discrepancy between any such output bit and the corresponding expected fault-free bit indicates at least one fault in the circuit.

Abstract: ABSTRACT     A laminated, adhesive backing material for application to the rear surface of mirrors to prevent shattering thereof.  The backing material of this invention is a three layer laminate which includes a central reinforcing layer sandwiched between two outer layers.  The central reinforcing layer typically includes a polyester scrim, while the two outer layers typically are formed of polypropylene.  An adhesive layer is provided on the outer surface of one of the outer layers of the laminate.  The backing of this invention exceeds a 400 foot/pound test requirement.  This backing material is manufactured by heat sealing the central reinforcing layer between the two outer layers and thereafter applying the adhesive to the outer surface of one of the outer layers.
